so im new on TypeScript and i need your guys help. im trying to build a module with typescript that does api calls that im later adding to my main project. so i was doing first with get requests with ajax. But i got this:

(node:1588) UnhandledPromiseRejectionWarning: TypeError: $.ajax is not a function

This is my Typescript File:

import * as $ from 'jquery'

class RedditJuice {

    afterbeforeStorage:Array<string>;
    totalPage:number
    currentPage:number


    constructor() {
        this.afterbeforeStorage = []
        this.totalPage = 0
        this.currentPage = 0


    }
    fetchRedditFeed = async (afterTag:string, beforeTag:string) => {
        return new Promise<JSON>((resolve, reject) => {
            console.log("yey")
            if(afterTag == null || undefined || "" && beforeTag == null || undefined || ""){
                var url:string = "https://reddit.com/.json"
            }
            else if(beforeTag != null|| undefined || ""){
                var url:string = "https://reddit.com/.json?after="   afterTag
            }
            else {
                var url:string = "https://reddit.com/.json?after="   afterTag   "?before="   beforeTag
            }
            $.ajax({
                url: url,
                type: "GET",
                success: function(getData){
                    console.log(getData.data)
                    resolve(getData.data) 
                },
                error: function(err){
                    reject(err)
                }
            })
        })
    }


    fetchPostComments = async (permalink:string) => {
        return new Promise<JSON>((resolve, reject) => {
            var comment_fetch_url = "https://reddit.com"   permalink   '.json?limit=10'
            $.ajax({
                type: "GET",
                url: comment_fetch_url,
                success: function(data) {
                    resolve(data[1].data)
                },
                error: function(err){
                    reject(err)
                }  
            })
        })
    }
}

const rApi = new RedditJuice() 

console.log(rApi.fetchRedditFeed("", ""))

On the buttom of the file im trying to use the class but then i get the mentioned error... And yes im running the .js file that is compiled by tsc. I also ofc installed jQuery with npm (@types/jquery)

Thanks for your support ^____^

CodePudding user response：

Are you executing this in a browser or in the nodejs vm either as a test or directly? jquery uses the XMLHttpRequest supplied by the browser environment to implement its ajax functionality and when it is unavailable it won't work.
